### Configure Tag Instances with Defaults in Yii2 UI

Source: https://context7.com/yii2-framework/ui-awesome/llms.txt

Demonstrates how to instantiate HTML tags with default configurations that merge with global factory defaults using Yii2 UI. Shows overriding global defaults with instance-specific settings.

```php
use yii\ui\html\flow\Div;
use yii\ui\factory\SimpleFactory;

// Set global defaults
SimpleFactory::setDefaults(Div::class, [
    'class' => 'global-class',
    'data' => ['source' => 'global']
]);

// Pass defaults during instantiation
$div = Div::tag([
    'id' => 'instance-id',
    'class' => 'instance-class',
    'title' => 'Instance title'
])->render();
// User defaults override global defaults for class
// Output: <div class="instance-class" id="instance-id" title="Instance title" data-source="global">
// </div>

// Combine instance defaults with method calls
$div = Div::tag(['class' => 'base'])
    ->id('custom')
    ->content('Hello')
    ->render();
// Output: <div class="base" id="custom">
// Hello
// </div>

// Instance defaults with nested structures
$div = Div::tag([
    'data' => ['level' => 1],
    'style' => ['color' => 'blue']
])
->dataAttributes(['extra' => 'value'])
->render();

// Clean up
SimpleFactory::setDefaults(Div::class, []);

### Building HTML Elements with Fluent Tag Classes (PHP)

Source: https://context7.com/yii2-framework/ui-awesome/llms.txt

Demonstrates how to use object-oriented tag classes in PHP to create HTML elements with fluent interfaces. Supports chaining attribute methods, using begin/end for structural tags, and nesting elements. Immutability is a key feature, ensuring configurations are not altered after creation.

```php
use yii\ui\html\flow\Div;
use yii\ui\html\phrasing\Span;

// Create a div with fluent methods
$div = Div::tag()
    ->class('container')
    ->id('main')
    ->content('Hello World')
    ->render();
// Output: <div class="container" id="main">
Hello World
</div>

// Chain multiple attribute methods
$styledDiv = Div::tag()
    ->class('card')
    ->style('padding: 20px; margin: 10px;')
    ->dataAttributes(['role' => 'panel', 'id' => 123])
    ->title('Information Card')
    ->content('<p>Card content</p>')
    ->render();
// Output: <div class="card" title="Information Card" data-role="panel" data-id="123" style="padding: 20px; margin: 10px;">
<p>Card content</p>
</div>

// Use begin/end with tag objects
echo Div::tag()->class('wrapper')->begin();
echo Span::tag()->content('Inner content')->render();
echo 'More content';
echo Div::end();
// Output: <div class="wrapper">
<span>Inner content</span>
More content
</div>

// Nested tag objects with immutability
$inner = Span::tag()->class('highlight')->content('Important');
$outer = Div::tag()
    ->class('container')
    ->content($inner->render())
    ->render();
```

### Factory Pattern for Global Defaults and Tag Instantiation (PHP)

Source: https://context7.com/yii2-framework/ui-awesome/llms.txt

Illustrates the `SimpleFactory` class in PHP for managing global configurations and instantiating tags. It allows setting default attributes for tag classes, which are inherited by new instances. User-provided attributes can override these defaults. The factory also supports dynamic configuration of tag instances.

```php
use yii\ui\factory\SimpleFactory;
use yii\ui\html\flow\Div;

// Set global defaults for a tag class
SimpleFactory::setDefaults(Div::class, [
    'class' => 'default-container',
    'data' => ['component' => 'ui']
]);

// All new instances inherit defaults
$div1 = Div::tag()->render();
// Output: <div class="default-container" data-component="ui">
</div>

$div2 = Div::tag()->id('custom')->render();
// Output: <div class="default-container" id="custom" data-component="ui">
</div>

// User attributes override global defaults
$div3 = Div::tag(['class' => 'override'])->render();
// Output: <div class="override" data-component="ui">
</div>

// Retrieve current defaults
$defaults = SimpleFactory::getDefaults(Div::class);
// Returns: ['class' => 'default-container', 'data' => ['component' => 'ui']]

// Configure a tag instance dynamically
$configured = SimpleFactory::configure(
    Div::tag(),
    [
        'id' => 'dynamic',
        'class' => ['card', 'shadow'],
        'content' => 'Dynamic content'
    ]
);
echo $configured->render();
// Output: <div class="card shadow" id="dynamic">
Dynamic content
</div>

// Clear defaults
SimpleFactory::setDefaults(Div::class, []);
```

### Rendering and Encoding HTML Attributes (PHP)

Source: https://context7.com/yii2-framework/ui-awesome/llms.txt

Explains the `Attributes::render()` method in PHP for processing attribute arrays. It handles automatic encoding, sorting, and type conversions for attributes, including basic, data, ARIA, and style attributes. This method is crucial for preventing XSS vulnerabilities.

```php
use yii\ui\helpers\Attributes;

// Basic attribute rendering with automatic ordering
$attrs = Attributes::render([
    'type' => 'text',
    'name' => 'username',
    'class' => ['form-control', 'input-lg'],
    'required' => true
]);
// Output:  class="form-control input-lg" name="username" type="text" required

// Data attributes expansion
$attrs = Attributes::render([
    'class' => 'widget',
    'data' => [
        'role' => 'user',
        'id' => 42,
        'config' => ['theme' => 'dark', 'lang' => 'en']
    ]
]);
// Output:  class="widget" data-role="user" data-id="42" data-config='{"theme":"dark","lang":"en"}'

// ARIA attributes for accessibility
$attrs = Attributes::render([
    'aria' => [
        'label' => 'Close dialog',
        'hidden' => 'false',
        'expanded' => 'true'
    ],
    'role' => 'button'
]);
// Output:  role="button" aria-label="Close dialog" aria-hidden="false" aria-expanded="true"

// Style attribute from array
$attrs = Attributes::render([
    'style' => [
        'color' => 'red',
        'font-size' => '14px',
        'padding' => '10px 20px'
    ]
]);
// Output:  style="color: red; font-size: 14px; padding: 10px 20px;"

// XSS prevention with automatic encoding
$attrs = Attributes::render([
    'title' => '<script>alert("XSS")</script>',
    'data' => ['value' => '"><script>evil()</script>']
]);
// Output:  title="&lt;script&gt;alert(&quot;XSS&quot;)&lt;/script&gt;" data-value="&quot;&gt;&lt;script&gt;evil()&lt;/script&gt;"
```
